(21) Electronic Volume Control Register Set
Through these commands, the liquid crystal driving
voltage V
circuit of the built-in liquid crystal power supply, in order
to adjust the contrast of the liquid crystal display.
By setting data to the 4 bit register, one of the 16 voltage
status may be selected for the liquid crystal driving
voltage V
voltage regulation range of the V
paragraph of the voltage regulation circuit in the Clause
for the explanation of functions.
When not using the electronic volume control function,
set to (0, 0, 0, 0, 0).
(22) Power Save (Complex Command)
If the Display All Points ON command is specified in the
display OFF state, the system enters the power save
status, reducing the power consumption to approximate
the static power consumption value. The internal state in
the power save status is as follows:
(a) The oscillator and power supply circuits are stopped.

(e) All LCD driver voltages are fixed to the V
The power save mode is cancelled by entering either the
Display ON command or the Display All Points OFF
command (display operation state). When external volt-
age driver resistors are used to supply the LCD driver
voltage level, the current through them must be cut off by
the power save signal.
If an external power supply is used, it must be turned OFF
using the power save signal in the same manner and
voltage levels must be fixed to the floating or V
Sequence in the Power Save Status
Power Save and Power Save Clear must be executed
according to the following sequence.
To give a liquid crystal driving voltage level by the
externally-installed resistance dividing circuit, the cur-
rent flowing in this resistance must be cut before or
concurrently with putting the S1D15600/601/602 series
into the power save status so that it may be fixed to the
floating or V
When using an external power supply, likewise, its
function must be stopped before or concurrently with
putting the S1D15600/601/602 series ino the power save
status so that it may be fixed to the floating or V
In a configurationinwhich an exclusive common driver
such as S1D16700 is combined with the S1D15600/601/
602 series, it is necessary to stop the external power
supply function after putting all the common output into
non-selection level.
